Thomas Henry Culhane This one is scary (or deliberately ironic) -- the Lennon sisters start doing a sing songy oopshoowaddywaddy version of Little Darlin' and then get interrupted because "women aren't supposed to sing rock and roll". They are forced by Dick Dale to sing a song "for their father, an old time tune" (Dick should know bette...r as the half Egyptian author of Misir Lou, which means "Egypt Lou" made refamous in Pulp Fiction, which challenged Arab and American patriarchal traditions by rocking out arab melodies in the 1950s )

Thomas Henry Culhane The results were, we got about 9 minutes of generator time (on a 2kW genset) from about 200 liters of kitchen-fed-biogas; most of the time was idling, but for about 2 minutes we were pulling about 500 watts running the Insinkerator. The implication is that we could use about 100 liters of biogas to do our daily food grinding.

Thomas Henry Culhane ‎8:30 AM, no heat loss overnight, but no heat gain. Avg. tank temp 30 C with slight stratification (31 top, 29 bottom). Interesting result; normally uninsulated tank would lose heat overnight (ambient temp 26 C) but composter (which reads 43 C) apparently maintained but did not raise temp. Will have to insulate tank no...w that we have this control data, and observe again.

 People will look back at this turn of the century achievement the way we look at The Wright Brothers and Charles Lindburgh's baby steps in the last century. Bravo Piccard et al.
Payerne, Switzerland (AFP) July 8, 2010 - A solar powered aircraft masterminded by a Swiss adventurer made history on Thursday as the first manned plane to fly around the clock on the sun's energy, bringing a step closer the dream of perpetual flight.

  A tip I learned for using those maddening .MOD video files your camera spits out in a video editing program: do NOT waste time or $ on conversion programs or the process of converting (which I used to do with ffmpegx). Simply rename the file with the .mpg extension, because it is, in fact, an

And while you are at it, make sure your computer does NOT hide extensions. Windows XP and 7 default to hiding them which allows malware companies to fool you into launching an .exe thinking it could be a .jpg or something. Uncheck the hide extensions box in folder options.

If that doesn't work (and mine didn't, because of some virus or something) turn on the "run" programs feature in the start menu (windows) and type in regedit, and go into your registry and search for all instances of "NeverShowExt" and delete them, then reboot. Microsoft supposedly knows that hiding extensions can get you into trouble, but they haven't done anything about it yet, so you will have to take action on your own!

  ‎11 hours in and the average temp of the 60 liters is now a balmy 32 for the whole tank (uninsulated), up from 25-26 this morning. Had to add 20 liters of 21 C water because of a slow leak inside the composter just now, averaging everything back to 30, and if the thermosiphon doesn't shut down overnight like last night due to water loss, we will see what temp we've achieved by morning.

 Congratulations to Solar CITIES International colleague Mike Rimoin (and his elephant-dung and other Woodlland Park Seattle "zoo-doo" derived bacterial friends) for successful backyard biogas production. It took 5 months and change and string of 96 degree days to get cooking, but hey, that's the Northwest! Mike, once... you get the solar heat exchanger going, it should work like a charm! Welcome to the club of birthday biogas bioneers!

The backyard biogas digester finally started producing gas! It only required 96 degree weather! Next steps are to insulate it to try to keep the bacteria warm during colder (more normal) conditions.

After 8 hours the compost heat exchanger has raised the temp of the entire 60 liter tank from 25 C to 30 C (mixing temp). The warm water is now thermosiphoning in at 35 C, the temp at the heat exchanger is 42 C. Lets see what happens in a few more hours and how hot we can get the tank. The goal is to be able to heat K...ilian's kiddie pool with the composter so he can splash around comfortably.

Why grass-clipping-based compost heat for the kiddie pool instead of direct solar? Because Germany is so cloudy and aerobic bacteria work day and night, sunny or cloudy. And compost IS solar energy -- trapped by the grass. The idea is that all that energy concentrated by photosynthesis shouldn't go to waste while it decays toward entropic ... See Morefertilizer. Capturing it makes the most sense, and doing so with the least investment is the starter -- obviously if we could do as Claris Pharmaceuticals showed me and Alexis Ringwald in India, and gasify it to use for running a boiler or an engine that would be even cooler, but lacking gasification technology simply insulating the compost bin with styrofoam and sticking a heat exchanger inside really does work!

Joseluis Ortiz
I COULDNT agree more..... with grass clippings only we have our compost up to 145 150 after 5 days of decomp, hope it all works out for you, also Thomas i shared your info with some friends and architect in India that do sustainable building. who knows they may need your expertise down there

That would be great JoseLuis, I loved my work in India with the India Youth Climate Network two years ago! That is where my biogas odyssey began.
Let me know how long your compost pile continues producing heat. We are also now almost 4 days in and the heat is good with grass clippings only. Have you put your heat exchanger in yet? That will of ... See Morecourse take the average temp in the pile down; the question is how long can the pile sustain adding heat to a heat remover like water, and can we get useful temps in useful periods of time to make it all worth it. I think getting 60 liters from 25 to 32 in a day isn't unreasonable. If we can heat Kilian's wading pool that would be a win. Right now his grandparents boil water on the electric stove and pour it in and that just isn't sustainable so we are all excited about this since the pool is in the garden near the composter.

Awesome nightime footage of Alvaro Silva's Solar South Central backyard biodigester breathing fire like a mythical dragon. Al, once you start storing the gas you will be able to use it to run a generator like I did yesterday. My internal tank slurry temp i...s now 29 C and I'm getting about 100 liters of stored gas a day. If I can get it up to 35 I should get 5 to 10 times that. My observation is that biogas pulses out in little spurts of pressure. I think that if we don't release the pressure by exhausting the producer tank to a collector it inhibits the next pulse. So each of those 30 second burns could be collected adding up. And, of course, if I were in L.A. I would paint the producer black to get maximum heat. Check the effluent temperature and tell us what it is, okay?

The experiments will continue...

Thomas Henry Culhane Hanna Fathy Rostom Mike Rimoin Here is how I have mounted my biogas regulator. The way I start the engine is that I close the choke and press the primer button on the back of the regulator a couple of times. Then I use the drill to start the engine. Once started I open the choke up and duct tape down the primer butt...on so it remains completely depressed, letting the maximum amount of biogas in. The other adjustments we spent so much time doing on your roof in Cairo don't seem to be critical -- open up the adjustment screw half way or so. I was using six bricks on my gas collector today, so about 27 kg pressure. I think mounting the regulator so you can access the primer button without burning your hand and without the regulator touching any hot metal parts is critical. I drilled two holes on the bottom frame to do so.

Thomas Henry Culhane Hanna Fathy Rostom Sometimes God gives us what appears to be a problem so we can find a better solution. No more start-pull cords or starter springs to break for us! A 21mm socketwrench key in a handdrill turns out to be the best way to start a biogas-modified engine. Remove the starter device completely. Remember t...he music band on the boat in Lake Tanganyika, how they started their generator with a rubber belt from the flywheel mounting? Instead you can turn the flywheel with a drill. If it is an AC drill, insulate the socket key with duct tape, if a battery powered DC drill, just use as is. Works like a charm!

Sabotage at the Edison plant (the whole operation burned to the ground) and World War I all hitting at the same time. By the time the war was over (the world's first industrial war, which used combustion engines for portability of the war machines wherever oil could be had or shipped) the infrastructure for continued oil use was in place and none had been built for an electric storage solution future.

Thomas Henry Culhane Amer Rabayah Sam Sal Hanna Fathy Rostom Joram Samaon The solution for electrical storage appears to have been solved (at the level we are working) by Thomas Edison in 1901 and improved to the point of commercial feasibility by 1912.

The Edison Storage Battery is guaranteed to be capable of developing 100 percent capacity at the end of four years."

 This article, "The lark sings no more" shows sadly how even though the German biogas industry originally was planned to use garbage to create biogas, the garbage mafia and perverse incentives due to policy and market distortions are trying to drive the biogas industry here to use monocropped corn as the feedstock, just... as the ethanol industry in the U.S. was driven away from switch grass and waste inputs. Unbelievable. Another reason why the home and community scale approach should be ramped up -- do you know any family with an insinkerator who would go out and buy corn to make biogas when they have kitchen garbage flowing out every day? Screw the supposed economies of scale of large scale operations -- it seems that path always leads to an undesirable outcome. Small is Beautiful.

Thomas Henry Culhane Since we only need to run the insinkerator 3 to 5 minutes daily (which my watt meter says consumes about 16 watt-hrs -- the unit draws 475 watts when grinding, but over the 3 to 5 minutes I don't register over 20 watt hrs total) it seems that we can run it on about 100 liters of biogas.

Thomas Henry Culhane ‎@d3adp001 Thanks for the tip d3ap, I'll try to test many different loads. The insinkerator issue is germane because we are trying to prove that it is worthwhile running an insinkerator to grind up the food waste despite its energy costs.

But you couldn't hammer them, weld them, join them etc. and none of the games have that critical element in a manipulable way: WATER. I seek a game (or will create one given enough time) that lets water and thermodynamics be manipulated along with materials. A generation will hopefully then grow up learning real engineering in a pleasurable way as well as learning possible histories.

Thanks for the great article, Bob. It's nice to see that some efforts have been made, albeit underfunded and lower-priority than what its potential upside might have been. I was speaking more generally about the killing of the electric car and the whole "global warming is just a myth cooked up by Al Gore" position our government we took for most of... See More the past decade or so. I see the post TH shared and wonder if a U.S. company could have been the leader in sustainable energy had we been a little less tied to Big Oil. From the article you posted, it sounds like the algae biofuel research program has been terminated. (Or did I read the term "closeout report" incorrectly?

That study was completed and the close-out was the publishing of all of their findings (from what I understand, anyway).

There has been constant research into the algae biofuels, though when oil was at $40 a barrel, clearly it was not a priority for everyone. Look at MIT's projects, for instance.

One of the challenges now is that government spending and private investors need to weed out the snake oil from true long term solutions. Just look up AlgaeLink - a perfectly promising looking technology that duped investors. Excess hype around "global warming", in my opinion, can only damage growth of alternatives.

We should be looking at ways to reduce our energy needs and lessen the impact on our planet - period. By tying this obvious long term need to a single concept of "global warming" - you risk the possibility that people can challenge that notion, then defend NOT doing things to help the planet.

Thomas Henry Culhane The frightening thing about this is that people in the gulf states are generally on the side of more drilling, the logic reportedly being, "if our fishing and tourism industries are totally killed off, the only viable industry we will have is our oil industry", so the worse this gets the more it paradoxically creates t...he incentive for greater, not less, exploitation of deep-sea oil. And this will continue -- the more our biosphere is destroyed the more we will feel it is time to get in there and rape what resources remain. If you really want to fight these polluting extractive industries you can not do it through the scare tactics of "consciousness raising disasters". You have to obviate the need for the products they are supplying. As Sheikh Yamani said, "the stone age did not end because we ran out of stones." Now get with the biogas, folks!

Thomas Henry Culhane
Before doing that, I would take a pH measurement. If it isn't acid it might not be overfed. Temperature could be your enemy. The best thing to do would be to take a few gallons of slurry and put them in an airtight container with a valve (a 5 gallon sealed paint bucket worked in Alaska; just put a valve in the lid). Let it sit in a really warm ... See Moreplace and see if you get gas. Another thing I did (because my system didn't produce for almost 3 months here) is add water to the system from the feeding pipe to create a kind of overpressure, then test the gas. Yesterday when I arrived from the U.S. and checked my valve I was getting negative pressure (suction) -- the tank was inhaling. So I thought "no gas". But then I started filling with water and this pushed the gas that was inside out -- and it lit. That is how I got the picture. It may be that your tank is indeed producing gas (I would suspect it is) but that you don't have a way to get the gas out (because the quantities are small because of the temperature -- remember these bacteria are optimized to work at body temp, 37 C. so before doing anything radical try those fixes. After all, the stuff in there is FOOD for bacteria, no reason to throw any of it out. If it is acid, try adding baking soda.
